D-REGION ELECTRON DENSITY MEASUREMENTS DURING THE SOLAR ECLIPSE OF 12 NOVEMBER 1966,

Abstract

Under the sponsorship of the Defense Atomic Support Agency (DASA), and in cooperation with the Brazilian Space Commission (CNAE), the National Aeronautics and Space Administration (NASA) and Sandia Corporation, the Ballistic Research Laboratories (BRL) instrumented and launched five Nike-Javelin III rockets from the southeastern coast of Brazil before and during the total solar eclipse of 12 November 1966. Each payload carried a nose-tip Langmuir probe for electron density and temperature measurements, two receivers to provide data for a partial reflection experiment and for differential absorption measurements, and a parachute-borne blunt probe (ejected from the payload at apogee) for positive and negative charge conductivity measurements. Electron densities derived from the Langmuir probe are presented as a function of time and altitude during the eclipse. Results from the other experiments have already been reported and are referenced. (Author)
